Another invasion of the Alemanni, of a more formidable aspect, but more glorious event, is mentioned by a writer of the lower empire. Three hundred thousand are said to have been vanquished, in a battle near Milan, by Gallienus in person, at the head of only ten thousand Romans. We may, however, with great probability, ascribe this incredible victory either to the credulity of the historian, or to some exaggerated exploits of one of the emperor’s lieutenants. It was by arms of a very different nature, that Gallienus endeavored to protect Italy from the fury of the Germans. He espoused Pipa, the daughter of a king of the Marcomanni, a Suevic tribe, which was often confounded with the Alemanni in their wars and conquests. To the father, as the price of his alliance, he granted an ample settlement in Pannonia. The native charms of unpolished beauty seem to have fixed the daughter in the affections of the inconstant emperor, and the bands of policy were more firmly connected by those of love. But the haughty prejudice of Rome still refused the name of marriage to the profane mixture of a citizen and a barbarian; and has stigmatized the German princess with the opprobrious title of concubine of Gallienus. III. We have already traced the emigration of the Goths from Scandinavia, or at least from Prussia, to the mouth of the Borysthenes, and have followed their victorious arms from the Borysthenes to the Danube. Under the reigns of Valerian and Gallienus, the frontier of the last-mentioned river was perpetually infested by the inroads of Germans and Sarmatians; but it was defended by the Romans with more than usual firmness and success. The provinces that were the seat of war, recruited the armies of Rome with an inexhaustible supply of hardy soldiers; and more than one of these Illyrian peasants attained the station, and displayed the abilities, of a general. Though flying parties of the barbarians, who incessantly hovered on the banks of the Danube, penetrated sometimes to the confines of Italy and Macedonia, their progress was commonly checked, or their return intercepted, by the Imperial lieutenants. But the great stream of the Gothic hostilities was diverted into a very different channel. The Goths, in their new settlement of the Ukraine, soon became masters of the northern coast of the Euxine: to the south of that inland sea were situated the soft and wealthy provinces of Asia Minor, which possessed all that could attract, and nothing that could resist, a barbarian conqueror.
